Subject: [PATCH v3 0/8] HID: MS and Logitech high-resolution scroll wheel support

A full explanation of why and what is in the v1, v2 patch thread here:
https://lkml.org/lkml/2018/11/22/625

v3 adds a better commit messages, m560 REL_HWHEEL_HI_RES support and a patch 
moved in the ordering. This is a full patch sequence because Benjamin's
magic scripts struggle with singular updates ;)

hid-tools patches to add the tests:
https://gitlab.freedesktop.org/libevdev/hid-tools/merge_requests/12

libinput support (unmerged):
https://gitlab.freedesktop.org/whot/libinput/tree/wip/hi-res-scrolling
If you want to 'feel' how it works, run sudo ./builddir/libinput-debug-gui
and watch the green/red scroll bars. On a device with hi-res scrolling the
green bar (scroll fractions) will move smoother than the red bar (wheel
clicks).

Tested with:
- Microsoft Comfort Optical Mouse 3000
- Microsoft Sculpt Ergonomic Mouse
- Microsoft Wireless Mobile Mouse 4000
- Logitech MX Anywhere 2S

And a few other mice that don't have that feature, so the testing was of
limited excitement.

Cheers,
  Peter
